db2_conn_error — Returns a string containing the SQLSTATE returned by the last connection attempt
$connection
] ) : string
db2_conn_error() returns an SQLSTATE value representing
the reason the last attempt to connect to a database failed. As
db2_connect() returns FALSE in the event of a failed
connection attempt, you do not pass any parameters to
db2_conn_error() to retrieve the SQLSTATE value.
If, however, the connection was successful but becomes invalid over time,
you can pass the connection parameter to retrieve
the SQLSTATE value for a specific connection.
To learn what the SQLSTATE value means, you can issue the following command
at a DB2 Command Line Processor prompt:
db2 '? . You
can also call db2_conn_errormsg() to retrieve an
explicit error message and the associated SQLCODE value.
sqlstate-value'
connectionA connection resource associated with a connection that initially succeeded, but which over time became invalid.
Returns the SQLSTATE value resulting from a failed connection attempt. Returns an empty string if there is no error associated with the last connection attempt.
Example #1 Retrieving an SQLSTATE value for a failed connection attempt
The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect().
<?php
$conn = db2_connect('badname', 'baduser', 'badpassword');
if (!$conn) {
print "SQLSTATE value: " . db2_conn_error();
}
?>
